R4mm+R7mm+R10mm

This is SO much better than me rounding the corners with scissors. I use laminate sheets a lot and would just trim the corners. This thing makes it so much easier. I can use this quickly, it's strong enough for the material and even looks nice and even.

This 3 in 1 corner rounder has been a great addition to my crafting tools. The three size options are very useful. Having R4mm, R7mm, and R10mm gives flexibility depending on the project, whether it’s cards, stickers, or laminated pieces. It punches clean, smooth corners without tearing the paper. The cuts are precise, and it works well on standard cardstock as well as thinner materials. The alignment is easy, so you don’t have to guess where the cut will land. The tool feels sturdy and well made. It requires a firm press but not excessive force, and it does not jam easily. It has held up well with repeated use. Overall, it is easy to use, versatile, and worth the money for anyone who does regular crafting or paper projects.

This is a handy little tool! I used it to round the corner of my child's gradutaion announcements because I'm cheap and didn't want to pay the exorbitant amount to buy announcements with rounded corners. :) Looked just as good as the ones we received from others that had the rounded corners and only took maybe 10 minutes to do a couple hundred. We have since used it to "fancy up" several things!

It's good. I like that it has different corner sizes and a corner hole punch. I wish it made clean cuts every time. I use it for cardstock paper. It could be sharper, but for the price, I'm not mad at it. It works well most of the time. You just have to be mindful of lining up the corners just right. You can sort of feel when the paper is aligned properly before pressing down. Overall, it met my needs. I can always upgrade to a different one later, but this is a really good start! I'll likely keep using this for a while.

Easy to use and cuts nice, clean rounded corners. I really like having 3 different sizes in one tool. Works exactly like I hoped!

The skin on my hands is hypersensitive, so I trim corners off of stiff documents, cards, etc. if I am going to handle them more than once. This 3-in-1 rounder is easy to use and heavy enough to not dance around when being used. Sometimes I end up with an irregular corner, but that might be my bad!

My fiancée is now getting into her “crafting era” she has been making inserts for her kindle and bookmarks out of scrapbook paper, this corner rounder has made it so much easier for her to cut the corners (literally) and make everything look super professional. Very easy to use and cuts well. Great price for a little product. Easy to store with all your other 100 crafting items

It is nice to have three corner radius options in one cutter. From the first day using it this week I noticed that the cutting areas do not always clear themselves of the cut photo paper debris, and I have to tap it each time to make sure the tiny pieces have exited or the cutter gives an odd shaped cut. Those can always be corrected, because the odd cuts are always smaller than the intended rounded cut shape. It's just a bit inconvenient to have to tap the cutter after each cut.

Resistente ! Cortes perfectos

Sadly it does not cut though laminated papers

Used it to round corners of my plastic laminated sheets. Good.

The easiest way to «cut corners» safely.

Hit and miss. Product does not consistently give clean edges. I might be able to get a successful punch 2/10 times. Product may be well made and sturdy, but the results are not of satisfactory standard.
